An object of the invention is to provide a portable storm window for a locomotive cab which is very inexpensive to manufacture, fits a number of locomotive windows and may be installed and removed with facility, rapidity and convenience.

Another object of the invention is to provide a portable storm window which is of light weight, highly portable and may be switched from one window to another in a locomotive cab.

Still another object of the invention is to provide a portable storm window for a locomotive cab which may be cleaned on its inside and outside surfaces while it is in the cab.

Yet another object of the invention is to provide a portable storm window for a locomotive cab which is wind, snow and rain tight and operates efficiently and effectively.

Another object of the invention is to provide a portable storm window for a locomotive cab which is structurally strong and rigid, and fits snugly and tightly in the frame of the cab window.

Another object of the invention is to provide a portable storm window for a locomotive cab which has a rear view mirror mounted therein.

In order that the invention may be readily carried into effect, it will now be described with reference to the accompanying drawing, wherein:

FIG. 1 is a schematic diagram of an embodiment of the portable storm window; and

FIG. 2 is a top view of the embodiment of FIG. 1.

In the FIGS., the same components are identified by the same reference numerals.

The portable storm window of the invention is for a window I ofa locomotive cab 2 (FIG. 1). The cab window 1 has slidable glass panels 3 and 4 (FIGS. 1 and 2) therein.

The storm window comprises a glass panelled box having an open side 5 (FIGS. 1 and 2) and dimensioned to fit into the maximum open area of the cab window 1 when said cab window is open. The storm window extends outward beyond the outside 6 (FIG. 2) of the locomotive at the cab window 1, as shown in FIG. 2.

The storm window further comprises a protruding strip 7 (FIGS. 1 and 2) around the open side 5 of the box. The protruding strip 7 is adapted to abut the inside 8 (FIGS. 1 and 2) of the locomotive 2 at the cab window 1.

A releasable fastening device (FIG. 1) is affixed to the protruding strip 7 for releasably affixing the storm window to the inside 8 of the cab window 1. The fastening device comprises two hooks 9 and 10 affixed to opposite sides 11 and 12 of the protruding strip 7 (FIG. 1). The hooks 9 and 10 are adapted to engage corresponding members 13 and 14, respectively, on the inside 8 of the locomotive 2 at the cab window 1. The members 13 and 14 are shown as posts or pins, although they may be eyes.

The box has a projecting strip 15 (FIG. 2) extending from one side 16 thereof adapted to fit into a corresponding groove 17 formed in a glass panel 18 (FIG. 2) of the cab window 1. The box has a groove 19 formed in an opposite side 20 (FIG. 2) thereof adapted to accommodate a corresponding projecting strip 21 (FIG. 2) of another glass panel 22 (FIG. 2) of the cab window 1 The box has a top 23 (FIGS. 1 and 2) sloping downward from the protruding strip 7 to provide drainage. The box has a bottom 24 (FIG. 1) and padding 25 on the inside of the box on the bottom to accommodate an arm of a person leaning in the storm window.

Weather stripping 26 (FIG. I) is provided on the surface of the protruding strip 7 adapted to abut the inside 8 of the locomotive 2.

A rear view mirror 27 (FIG. 1) is adjustably mounted in the box.

While the invention has been described by means of specific examples and in specific embodiments, I do not wish to be limited thereto, for obvious modifications will occur to those skilled in the art without departing from the spirit and scope of the invention.
